I have just bought the Acer AL2671W and must admit that it is a stunning piece of equipment. Television is set up and picture and sound is perfect. However when linked to my PC with VGA I get no sound. I see that the audio in needs to connect to the audio output of my PC with DVI or VGA connector. Could someone clarify that for me. I am not sure of what I have to buy to enable sound on the PC side. My Seventy something old head is just not functioning sensibly anymore. Thanks for any help.
